This study examines Liu Zhenyun’s 2026 novel Xian de Wanjiao and explores how everyday trivialities become concrete sites for the production of absurdity, and how such absurdity is further articulated through the narrative form of black humor. Methodologically, the study is based on close reading and focuses on key scenes and recurring narrative patterns throughout the text. The analysis shows that the novel reveals the loosening of causal order, the disjunction between naming and reality, and the inversion of everyday logic through ordinary details of daily life, such as money management, acts of naming, the seasoning of food, the form of gifts, and casual conversation. At the same time, through the collapse of authority and order, the instability of relationships and meaning, and laughter as a strategy of survival, the novel transforms imbalanced everyday experience into a black-humorous narrative structure. In this sense, black humor in Xian de Wanjiao is not an additional rhetorical ornament attached to absurdity, but a central expressive form through which an unstable reality is perceived and narrated. Particularly noteworthy is that laughter in the novel does not function to solve problems; rather, it operates as a minimal strategy of survival that enables the characters to continue living amid disordered relationships, unstable meaning, and the collapse of authority. Ultimately, Xian de Wanjiao shows that everyday trivialities are not merely the background of absurdity, but the very space in which absurdity is generated and unfolds, while black humor constitutes the key narrative form through which this lived reality is represented.
